Comparing frozen saphenous vein with Gore‐tex in vascular access for chronic hemodialysis

Abstract

Performing chronic hemodialysis in patients suffering from end-stage renal disease needs a suitable vascular access like arteriovenous fistula in the upper limbs and bridge fistula in the upper or lower limbs, and also use of permanent and temporary catheters. The purpose of this study is to compare frozen saphenous vein versus using synthetic Gore-tex vascular graft for A-V fistula. In the prospective randomized study, 70 patients needing for dialysis access were randomly divided into two groups. We performed the frozen saphenous vein A-V fistula in the test group and the Gore-tex fistula in the control group. An assessment included function criteria (fistula thrill and murmur) and complications (infection and thrombosis) in planned intervals. At the end of the follow-up period, the flow rates of all fistulas were assessed by Doppler sonography. The data were compared. Comparing the function criteria (fistula murmur and thrill) and the flow rate of the test group (frozen saphenous A-V fistula) and the control group (Gore-tex method) showed no significant difference and also no significant difference between two groups in thrombosis. Infection rate of the Gore-tex method was significantly high (p < 0.05). Arteriovenous fistula was an acceptable alternative in chronic hemodialysis, and frozen saphenous vein arteriovenous fistula was superior to Gore-tex arteriovenous graft in some aspects.

Alternative Grafts for Brachioaxillary Hemodialysis access: Saphenous Vein Versus Synthetic Graft (Comparative Study)

“…Schneider et al depicted 309 instances of AVF made utilizing a wide range of benefactor conduits and receptor veins in upper appendages with rationed SV unites, demonstrating that essential and auxiliary patency rates were like those revealed in the writing on prosthetic unions [23]. In a gathering of 70 patients whose AVF included various locales in upper appendages and utilized monitored SV or prosthetic unions (Gore-Tex), Mousavi et al watched no distinctions in useful standards, patency rates, or event of apoplexy yet they reported an essentially higher recurrence of disease in patients rewarded with prosthetic [24] which coordinate with our investigation as 3 unions (10%) has been tainted , however in our examination , there is a contrast between the two gatherings regarding patency and join apoplexy .…”

Recruitment into randomised trials of arteriovenous grafts: A systematic review

“…The numbers of patients recruited differed in two RCT between the abstract and the results section (numbers of patients: 39 vs 40; 60 vs 70). 20,39 The fuller results section imply an error in the abstracts, and the later number used in analysis.…”
